Is Lydiah a boy’s or a girl’s name?

Girls and boys named Lydiah: the SSA national file counts each sex separately.
How many people are named Lydiah, and how old are they?
An estimated 310 Americans named Lydiah and born in the U.S. are alive in 2026 (99% of everyone recorded); the median is 13 years old and half are between 9 and 18. An estimate from SSA’s births and life tables, not a count.
The 2020 Census counted 361 people named Lydiah (361 women and girls, 0 men and boys). SSA’s births carried forward to Census day, April 1, 2020, predict 273 born in the U.S. The Census count is 32% above that prediction. Possible reasons: the Census counts people born abroad, whom SSA’s files leave out, and it records the name people give, which SSA may have recorded under another spelling or as part of a compound name.
Living estimate: SSA births carried forward with the survival rates in SSA’s cohort life tables (2024 Trustees Report) for each birth year and sex. How the estimate is made.
